LвЂ‰DESIGN FEATURES Compact Solution for Hot Swap and
Supply Monitoring in CompactPCI
and PCI Express Systems by Pinkesh Sachdev
Introduction
Servers that operate in critical
industrial applications, such as communications and data-storage, must
do so with near-zero down-time. Such
high availability systems cannot be
shut down to replace or upgrade circuit
boards, so Hot Swap capabilities are
paramount. Once a board is in the
system, it is also important to continually monitor its power consumption to
anticipate board failure. The LTC4245
makes it easy to satisfy both the Hot
Swap and monitoring needs of high
availability systems. It incorporates
a quad-supply Hot Swap controller
and an 8-bit ADC for board supply
voltage and current monitoring. Access to supply monitoring data is via
an I2C-compatible interface.
The LTC4245 is designed to be used
in a CompactPCI (CPCI) Hot Swap
board, where the four supplies are …
